Abstract (en)

A vinyl chloride-grafted ethylene copolymer superior in adhesiveness both to metal, glass and polar high molecular materials such as polyamides and to non-rigid vinyl chloride resins is provided, in which the backbone polymer is a copolymer of ethylene, (meth)acrylic ester and unsaturated dicarboxylic acid anhydride and the pendant polymer is a vinyl chloride polymer. This copolymer is produced by graft-polymerization of vinyl chloride onto the ethylene-(meth)acrylic ester-anhydride copolymer.
